Hello! I have an 180000 Gallon Inground pool. I'm looking to get any feedback anyone might have on the Heat pump I'm looking at installing. I've selected a RayPak Crosswind V 138K BTU. I just want to extend the season a little. Perhaps Early May to Late September. The pool is in full sun. I selected RayPak for it's reputation, plus it has onboard wifi capability. It 138K BTUs generally enough to heat the pool reasonably?
